Delta Dental of California has started covering tooth implants and extra cleanings, and exams for pregnant women.

California Dental, San Francisco, says it will add the benefits as standard benefits for all fully insured, fee-for-service clients based in California, at no extra cost.

Eventually, California Dental and affiliates will make the new standard benefits available for commercial clients in 15 other states and the District of Columbia, California Dental says.
